What a great clip; Quick release button, rubber jaws, long reach, light weight and damn durable! It's not as dangerous as the C-Clamp and not as fast as the one-handed clamp, but this clamp combines two ideas: it has better traction on and around edges like the C-Clamp, and it's very quick and easy to use, but you need two hands to install. I think I'll buy a few more.!
